Radiochemical neutron activation analysis has been used to determine the concentration of 36 elements in neuromelanin, 22 elements in substantia nigra, and 32 elements in putamen of healthy subjects without signs of neurological disorders. Substantia nigra and putamen tissues were carefully dissected from the brain using special surgical instruments and(More)
Description: The Handbook of Nanotoxicology, Nanomedicine and Stem Cell Use in Toxicology provides an insight into the current trends and future directions of research in these rapidly developing scientific fields. Written by leading scientists and experts, the Handbook will be of interest to various scientific disciplines including toxicology, medicine,(More)
There is concern about the possible toxicity of palladium nanoparticles (Pd-NP), as they are released in the environment through many applications. We previously studied the toxicity of Pd-NP at high concentrations; here we address the possible toxicity of Pd-NP at low, subtoxic doses. In particular, we have exposed normal human PBMC entering into the first(More)
Almost all people in developed countries are exposed to metal nanoparticles (MeNPs) that are used in a large number of applications including medical (for diagnostic and therapeutic purposes). Once inside the body, absorbed by inhalation, contact, ingestion and injection, MeNPs can translocate to tissues and, as any foreign substance, are likely to(More)
We have considered nanoparticles (NPs) of Fe, Co and Ni, three transition metals sharing similar chemical properties. NP dissolution, conducted by radioactive tracer method and inductively coupled plasma mass spectrometry, indicated that NiNPs and FeNPs released in the medium a much smaller amount of ions than that released by Co NPs. The two considered(More)
Box plots are used in the visual representation of large data sets and in exploratory data analysis. They display batches of data with five values being used to describe the data set. These are the median, the upper and lower extremes of the range of values and the 75 and 25 percentiles. A notch about the median, e.g. at the 95 percent level of(More)
